Cannabis Accounting Firms: A 2026 Guide to 280E, COGS and Audit-Ready Records
If you've ever looked at your tax bill and wondered if someone made a mistake, you're not imagining it. Cannabis operators subject to Section 280E can face federal tax burdens far above those of conventional businesses. It's because of a single, punishing section of the tax code that was never written with a state-legal industry in mind.
In 2026, however, the first question is no longer simply how 280E works. It is whether and where 280E still applies to your business. Federal treatment now differs between qualifying medical marijuana activity and adult-use activity, making license structure, product classification and recordkeeping even more important.
The right cannabis accounting firm can help determine how the current rules apply to your business, identify costs that may properly be included in cost of goods sold and build the records needed to support your tax positions. But that work depends on the quality of the operational and financial data behind it.
Let's walk through what 280E does, how federal changes in 2026 affect different cannabis operators, what may be included in COGS, what a cannabis accounting firm needs from you and where the records that make all of this defensible actually come from.
The 280E Problem and Who It Still Affects
Section 280E of the Internal Revenue Code denies standard business expense deductions to businesses trafficking in Schedule I or II controlled substances. It was written in 1982, decades before any state had legalized cannabis for medical or adult use.
That treatment changed for part of the industry in 2026. Effective April 28, 2026, marijuana covered by a qualifying state medical marijuana license, along with FDA-approved marijuana products, was placed in Schedule III. The final rule states that qualifying state licensees are no longer subject to the deduction disallowance imposed by 280E, although it also advises businesses to consult tax counsel regarding how the rule applies to their individual circumstances.
Marijuana outside those categories, including adult-use activity, remains in Schedule I while the broader federal rescheduling process continues. Businesses with both medical and adult-use operations should not assume that one answer applies to the entire company. The treatment may depend on which licenses, products, activities and entities fall within the Schedule III rule.
For a conventional business, expenses such as rent, payroll, marketing and insurance generally reduce taxable income. For a cannabis business or activity still subject to 280E, many of those ordinary business expenses cannot be deducted. As a result, federal taxable income may be calculated much closer to gross profit than net income, and the difference can put significant pressure on margins and cash flow.
That is why cannabis-specific accounting experience matters. Safe Harbor provides cannabis bookkeeping and back-office support directly to operators, including reconciliations, financial reporting, accounting-system setup, tax-reporting readiness and audit-ready recordkeeping. Safe Harbor also evaluates how current federal and state rules affect each operator's financial structure, accounting processes and tax position.
The complexity increases for operators managing more than one license, entity or state. In 2026, those businesses may also need to distinguish medical activity from adult-use activity and maintain records that support the treatment applied to each part of the operation.
Cannabis accounting requires experience with tax rules, licensing structures and operational systems that many general accounting firms encounter infrequently. Applying conventional business logic without understanding 280E, COGS and the 2026 scheduling changes can lead an operator to overpay taxes or take positions that are difficult to support if examined.
Cannabis accounting is a specialty because the rules are genuinely different, and the cost of getting them wrong can include unnecessary tax expense, penalties, professional fees and increased audit risk.
For businesses still subject to 280E, one distinction remains especially important: the treatment of cost of goods sold.
What You Can and Cannot Deduct: COGS Explained
For businesses still subject to 280E, many operating-expense deductions remain unavailable, but those businesses may still account for cost of goods sold when calculating gross income. Technically, COGS is an adjustment to gross receipts rather than a standard business-expense deduction.
Qualifying medical marijuana businesses that are no longer subject to 280E may have access to ordinary business deductions, subject to the normal tax rules and the specific facts of the business. COGS remains important for those operators because it affects gross profit, inventory valuation, margins and financial reporting even when 280E does not apply.
Cost of goods sold generally includes eligible costs incurred to acquire or produce the inventory a business sells. Exactly which costs qualify depends on the operator's activities, accounting methods, license type and applicable tax rules. Operators should not assume that every expense connected to production can automatically be included.
The treatment also differs depending on where the business sits in the supply chain. A cultivator or manufacturer may have eligible production costs that a retailer does not. A dispensary's COGS is generally more closely tied to inventory acquisition and other allowable inventory costs.
This is where a properly prepared COGS analysis can earn its cost. A defensible analysis documents which costs were included, why they were included, how they were allocated and which records support the calculation.
Get it too conservative and you may overpay. Get it too aggressive without documentation and you may create a tax position that is difficult to defend.
Consider two cultivators with identical revenue and similar operations. One tracks materials, production labor, facility usage and inventory movement as activity occurs. The other estimates those costs at year-end based on broad percentages.
Both may report similar COGS on paper. Only one has a detailed record showing how the number was developed.
The COGS analysis is a financial exercise. The information supporting it is generated through daily operations. That is where accounting systems and operational systems must connect.
COGS by License Type: Cultivator, Manufacturer, Distributor and Dispensary
The mechanics of COGS vary by license type. Your cannabis accounting firm should understand what your business actually does, not simply apply a generic cannabis-industry percentage.
Cultivators
Cultivators generate detailed production data across plants, rooms, batches and harvests. Potential inventory costs may include eligible materials, direct production labor and other properly allocable production costs, depending on the facts and applicable accounting rules.
The challenge is capturing those costs consistently as inventory moves through the cultivation cycle. Waiting until year-end often leaves the accounting team trying to recreate months of activity from incomplete records.
Manufacturers and Processors
Manufacturers and processors must track how raw materials, ingredients, packaging and production activity move into finished products. Costs may need to be assigned across production runs, batches, SKUs and brands.
The appropriate treatment depends on the nature of each cost and how it relates to production. The more products or brands that share a facility, the more important a consistent, documented allocation methodology becomes.
Without one, costs associated with one product can easily be assigned to another or left out altogether.
Distributors
Distributors need organized records covering inventory acquisition, receiving, transfers, warehousing, sales orders and the movement of products between customers or locations.
Distribution models vary considerably by state, so the accounting treatment should reflect the operator's actual activities rather than assumptions based solely on the license name. A distributor handling multiple brands or entities also needs records that clearly separate the costs and activity associated with each.
Dispensaries and Retailers
Dispensaries typically have less flexibility than cultivators or manufacturers because their COGS is largely tied to the acquisition of inventory and other allowable inventory costs.
That makes accurate purchase, receiving and inventory records especially important. When a retailer has little room for error, incomplete records or unreconciled inventory can materially affect both the books and the tax return.
Safe Harbor Financial provides and manages cannabis accounting work across these license types, including COGS analysis, allocation methodologies, bookkeeping, tax support and the documentation needed to support financial and tax positions. Depending on the engagement, the work is performed by Safe Harbor's in-house team or managed by Safe Harbor through its partner network. In either model, Safe Harbor oversees the relationship and delivery of the work.
Safe Harbor also provides strategic finance for cannabis businesses, including financial and tax strategy, forecasting, reporting, multi-entity allocations and CFO-level guidance. That broader perspective helps operators understand not only what may be supportable for tax purposes, but how margins, cash flow and operating decisions affect the business throughout the year.
How Your Operational Data Feeds Your Accounting
A COGS analysis is only as defensible as the records behind it. If an operation runs on spreadsheets, disconnected point-of-sale exports and a shared drive full of invoices, the accounting team may have to reconstruct the data before it can begin the higher-value financial and tax work.
That reconstruction takes time, can increase professional fees and introduces opportunities for error. A spreadsheet may be manageable for one license operating from one location. It becomes far less reliable when production spans multiple rooms, batches, brands, entities or facilities.
For operators with both medical and adult-use activity, clean operational data may now serve another purpose: helping the accounting team determine which products, sales and costs relate to each part of the business. That distinction may be critical when evaluating where 280E continues to apply.
This is where Distru fits into the accounting process, even though Distru is not an accounting or tax product.
Distru is a cannabis ERP that tracks inventory, production, purchase orders, sales orders and compliance activity as part of the operator's daily workflow. It tracks cost accounting as inventory moves through the facility rather than requiring the business to reconstruct everything at the end of the reporting period.
That can provide an accounting team with:
- Batch-level cost records captured as materials move through production
- Metrc-reconciled inventory records
- Purchase-order and sales-order history
- Transfer and manifest documentation
- A transaction trail connecting inventory activity with the financial records
- Records that may help distinguish activity across licenses, entities, products and locations
None of this replaces the accounting team or determines the appropriate tax treatment. Safe Harbor's accounting team must still evaluate the records, apply the relevant rules and determine how costs and activities should be treated.
What the operational system does is provide organized source data rather than an assortment of spreadsheets, exports and PDFs that must be reconciled manually.
Distru reports that its operators save more than 2,000 hours annually through compliance automation alone. Its Metrc integration communicates with Metrc in real time, helping keep operational and compliance records synchronized.
Think about what this can mean at tax time. An accounting engagement that begins with disconnected invoices, spreadsheets and a point-of-sale export may spend its first several weeks determining what happened during the year. An engagement that begins with organized, reconciled, batch-level records can move more quickly into COGS analysis, reporting and tax strategy.
What to Look for in a Cannabis Accounting Firm
Not every accounting firm that says it works with cannabis clients has the same level of experience. Before hiring one, ask questions that reveal whether the firm understands your license type, operating structure and financial systems.
1. Have you handled accounting and COGS analysis for my license type?
General cannabis experience is not the same as experience with your specific business model. A dispensary, cultivator, manufacturer and distributor each generate different records and face different accounting questions.
Ask specifically whether the provider understands the current federal distinction between qualifying medical marijuana activity and adult-use activity.
2. How do you approach cost capitalization and COGS?
The firm should be able to explain its process clearly, including what records it will review, how it develops allocation methodologies and how it documents its conclusions.
3. What operational records will you need, and how often?
If the answer is "send everything at year-end," ask more questions. Strong cannabis accounting work depends on ongoing access to reliable inventory, production, purchasing and financial information.
4. How will you support the work if a tax position is examined?
Ask what documentation the firm provides and what role it will play if questions arise later. The answer should make clear what is included in the engagement, how the underlying analysis will be documented and what additional support may be available.
5. How do federal scheduling changes and state tax rules affect my business?
Federal 280E treatment now depends partly on whether activity falls within the 2026 Schedule III rule for qualifying medical marijuana. States also differ in how closely they follow federal tax treatment. A cannabis accounting firm should evaluate the federal and state rules affecting each license, entity and market in which you operate.
6. Can you work with our existing operational systems?
Your accounting provider should understand how data flows from your ERP, inventory platform, point-of-sale system, banking activity and general ledger. The goal should be a reliable financial record, not another disconnected spreadsheet.
A cannabis specialist should have clear, specific answers to these questions. Experience matters because cannabis accounting is narrow, technical work with consequences that extend well beyond the tax return.
Financial and Operational Data Working Together
Cannabis operators often manage the financial and operational sides of the business as separate functions. In reality, they depend on one another.
Get the financial strategy right without clean operational data behind it, and you may have a tax position that is difficult to support. Keep the operational data organized without connecting it to the accounting process, and you may still leave legitimate COGS unrecognized or make decisions based on incomplete financial reporting.
Distru captures operational activity across inventory, production, purchasing, transfers and compliance. Safe Harbor provides and manages the financial layer, including bookkeeping, accounting, COGS analysis, tax support, financial reporting and strategic finance.
When those layers work together, Safe Harbor receives organized operational records instead of reconstructing activity from spreadsheets and year-end exports. That creates a stronger foundation for COGS analysis, more reliable reporting and better-informed financial decisions.
It can also help businesses operating across medical and adult-use markets maintain the separation and documentation needed to evaluate how the current federal rules apply.
Safe Harbor has processed more than $36 billion in depository activity and supports cannabis businesses across 41 states and territories. Distru supports hundreds of licensed operators with the systems used to manage inventory, purchasing, production and Metrc compliance.
Together, the two platforms connect what happens inside the operation with the books, tax positions and financial decisions that follow.
If you are responsible for defending a margin calculation or explaining financial performance to a board, lender or investor, that connection matters. It can be the difference between a number supported by reliable records and one that still depends on assumptions.
280E Resources for Cannabis Operators
The application of 280E changed materially in 2026, but the change does not affect every cannabis business in the same way. It is not something most operators can address through a single article or a once-a-year conversation.
A few practical steps can strengthen your position:
- Determine whether your licenses and activities fall within the 2026 Schedule III rule for qualifying medical marijuana.
- If you operate in both medical and adult-use markets, establish processes for separating the relevant products, revenue, costs and activities.
- Talk to a cannabis-specific accounting provider well before your next filing deadline.
- Confirm how each state in which you operate treats 280E and conforms to federal tax changes.
- Keep inventory, production, purchasing and compliance records current throughout the year.
- Reconcile operational systems with the general ledger and banking activity regularly.
- Document allocation methodologies instead of relying on unexplained year-end percentages.
- Revisit your financial structure as you add licenses, entities, products or locations.
- Make sure your operational and accounting teams agree on which system contains the authoritative record for each type of data.
The objective is not simply to produce a tax return. It is to create a connected financial and operational record that supports the return, improves visibility and gives management greater confidence in the numbers.
